Facing a plumbing overhaul can feel overwhelming, especially when you are trying to pin down exactly how much money you need to set aside. Whether you are building a new home or dealing with aging pipes that are ready to burst, understanding the 2018 plumbing installation costs to plumb or repipe a house is the first step toward a stress-free renovation. In this guide, we break down the real numbers, material choices, and labor factors that defined the market in 2018, helping you make an informed decision without breaking the bank.
What Was the Average Cost to Plumb or Repipe a House in 2018?
When homeowners ask about the total price tag, the answer varies significantly based on the size of the home and the materials chosen. In 2018, the national average for a whole-house repipe ranged between $1,500 and $15,000, with most standard single-family homes falling in the $4,000 to $8,000 sweet spot.
New construction plumbing installation typically cost slightly less per linear foot than repiping an existing home because contractors did not have to deal with the labor-intensive process of opening up finished walls and repairing drywall afterward. However, the complexity of the fixture count (sinks, toilets, showers) played a massive role in the final invoice.
Key Cost Drivers in 2018
- Home Size: A 1,500 sq. ft. home generally cost between $3,000 and $5,000, while a 3,000+ sq. ft. estate could easily exceed $12,000.
- Number of Stories: Multi-story homes required more vertical labor and longer pipe runs, increasing costs by approximately 20–30%.
- Wall Accessibility: Homes with slab foundations or finished basements required more destructive access methods, raising labor fees.
How Did Material Choices Impact 2018 Plumbing Prices?
The type of pipe you choose is the single biggest variable in your budget. In 2018, the industry was in a transitional phase where traditional copper was still popular but facing stiff competition from flexible plastics like PEX due to rising metal costs.
Copper vs. PEX vs. CPVC: A 2018 Price Comparison
| Material | Avg. Cost per Foot (Material + Labor) | Pros | Cons | Best Use Case | | :— | :— | :— | :— :— | | Copper | $8.00 – $12.00 | Durable, adds home value, resistant to UV. | Expensive, requires soldering, prone to theft. | High-end builds, exposed piping. | | PEX | $4.00 – $7.00 | Flexible, freeze-resistant, fast installation. | Cannot be used outdoors, vulnerable to rodents. | Whole house repipes, retrofits. | | CPVC | $3.50 – $6.00 | Cheap, easy to cut and glue. | Becomes brittle over time, noisy water flow. | Budget renovations, DIY repairs. |
In 2018, PEX (Cross-linked Polyethylene) became the dominant choice for repiping projects. Why? Because it reduced labor time by up to 40% compared to copper. Since plumbers often charge by the hour (averaging $70 to $120 per hour in 2018), the speed of PEX installation resulted in significant savings for the homeowner.
Expert Insight: According to industry data from 2018, switching from copper to PEX could save a homeowner an average of $3,000 on a standard 3-bedroom home repipe.

What Factors Influenced Labor Rates for Plumbing Installation?
Labor accounted for roughly 60% to 70% of the total plumbing bill in 2018. Understanding what drives these rates can help you negotiate or plan better.
1. Geographic Location
Plumbing costs were not uniform across the US. In major metropolitan areas like New York City or San Francisco, labor rates soared to $150+ per hour due to the high cost of living and strict union regulations. Conversely, in rural areas of the Midwest, rates hovered closer to $60 per hour.
2. Permit and Inspection Fees
Many homeowners forget to budget for the “paperwork.” In 2018, municipal permits for a whole-house repipe ranged from $200 to $1,000 depending on the city. This fee ensures the work meets local building codes and includes mandatory inspections. Skipping this step is illegal and can void your home insurance.
3. Emergency vs. Scheduled Work
If your pipes burst and you need immediate service, expect to pay a premium. Emergency call-out fees in 2018 often added a flat rate of $150 to $300 on top of the standard hourly labor, plus overtime charges if the work occurred nights or weekends.
Step-by-Step: The Process of Repiping a House
If you decide to move forward with a repipe, knowing the workflow helps manage expectations regarding timeline and disruption. Here is the standard procedure followed by professional plumbers in 2018:
- Initial Assessment and Quote: A licensed plumber inspects the current system, identifies leak points, and measures the linear footage required. They provide a detailed written estimate.
- Permit Acquisition: The contractor pulls necessary permits from the local city hall. This usually takes 2–5 business days.
- Water Shut-off and Drainage: The main water supply is turned off, and the existing system is drained completely.
- Demolition (Access Creation): Small holes are cut into drywall or ceilings to access old pipes. In 2018, pros used specialized cameras to minimize the number of holes needed.
- Old Pipe Removal and New Installation: Old galvanized or polybutylene pipes are removed. New PEX or copper lines are run through the walls. Note: For PEX, installers typically use ½ inch lines for fixtures and ¾ inch lines for main distribution.
- Pressure Testing: Before closing walls, the system is pressurized (usually to 80 PSI) and left for 24 hours to ensure no leaks exist.
- Wall Repair and Cleanup: While some plumbers offer patching services, many homeowners hire a separate drywall contractor to finish the walls and paint.
- Final Inspection: The city inspector verifies the work, and the permit is signed off.
Is It Better to Repair or Repipe Entirely?
This is the million-dollar question. In 2018, the general rule of thumb was: If your home has galvanized steel or polybutylene pipes, repipe immediately. These materials have a lifespan of 40–50 years and were prone to corrosion and sudden failure.
Signs You Need a Full Repipe
- Discolored Water: If your water looks rusty or brown, your iron pipes are corroding from the inside.
- Low Water Pressure: Buildup inside old pipes restricts flow, affecting showers and faucets.
- Frequent Leaks: If you are calling a plumber more than twice a year for different leaks, a repipe is more cost-effective than constant patches.
- Noisy Pipes: Banging or clanking sounds (water hammer) often indicate loose or deteriorating supports and pipes.
If your home only has one isolated leak in a relatively new copper system, a targeted repair is likely sufficient. However, for systems older than 50 years, a full replacement adds significant value to your home and prevents catastrophic water damage.
Frequently Asked Questions (FAQ)
1. How long does it take to repipe a house?
For an average 3-bedroom home, a professional team can complete a whole-house repipe in 2 to 5 days. The timeline depends on the number of bathrooms and the accessibility of the pipes. Using PEX usually speeds up the process compared to copper.
2. Does homeowners insurance cover repiping costs?
Generally, no. Homeowners insurance covers sudden and accidental damage (like a burst pipe flooding your floor), but it does not cover the cost of replacing old, deteriorating pipes as a maintenance upgrade. However, if a pipe bursts and damages your drywall, the damage repair might be covered, just not the pipe replacement itself.
3. Can I live in my house while it is being repiped?
Yes, most families stay in their homes during the process. Plumbers will shut off the water for short intervals (usually 4–6 hours at a time) to swap out sections of the system. They typically schedule these shut-offs during the day so you have water in the evenings.
4. What is the lifespan of PEX piping installed in 2018?
PEX piping is expected to last 40 to 50 years or more. It is highly resistant to scale and chlorine, does not corrode, and handles freezing temperatures better than copper, making it a durable long-term investment.
5. Will repiping increase my home’s resale value?
Absolutely. A documented whole-house repipe is a major selling point. It assures buyers that they won’t face immediate plumbing bills. In 2018 market analyses, homes with updated plumbing often sold faster and commanded a higher price compared to those with original galvanized pipes.
6. How do I find a reputable plumber for this job?
Look for licensed, bonded, and insured contractors with specific experience in repiping. Ask for references from jobs completed in the last year. Always get at least three written estimates before signing a contract.
Conclusion
Navigating 2018 plumbing installation costs to plumb or repipe a house requires a clear understanding of materials, labor rates, and the long-term value of your investment. While the upfront cost of $4,000 to $15,000 may seem steep, replacing failing pipes protects your home’s structure, improves water quality, and boosts resale value. Whether you choose the durability of copper or the cost-efficiency of PEX, acting sooner rather than later saves money on emergency repairs down the road.
